Take my chemistry class — where units, signs and mechanisms all have to be right

Chemistry earns its reputation as a weed-out course honestly. It asks you to hold several things in mind simultaneously — a quantitative calculation, the units that calculation is carried in, and the physical model the numbers describe — and it offers no credit for getting two of the three right. A stoichiometry problem with a perfect setup and a dropped conversion factor is simply wrong. An equilibrium answer with the right expression and a sign error is wrong. And organic chemistry adds a whole second language of structures and electron-pushing on top. Online, without a lab section or an instructor catching your slip at the board, the margin for error narrows further still.

This page lays out how we handle chemistry coursework properly: the topics we cover across the general and organic sequences, the platforms your homework lives in, how we treat lab reports and calculations, and where our honest policy applies to timed tests. The work goes to someone who genuinely thinks like a chemist, because in this subject that's the only thing that reliably produces right answers. Students rarely open with a paragraph of context — the first line is usually just take my chemistry class for me, I am two mechanisms behind.

Topics we cover

Chemistry sequences build steeply, so where you're stuck tells us a lot. We cover the arc.

General chemistry

Stoichiometry and the mole concept, atomic structure and periodic trends, chemical bonding and molecular geometry, gas laws, thermochemistry, solutions and concentration, chemical equilibrium and Le Chatelier's principle, acids and bases and pH, and electrochemistry. These are the foundations everything later leans on, and most gen-chem struggles trace back to one of them.

Organic chemistry

The course with its own reputation for fear. Nomenclature, structure and isomerism, reaction mechanisms and electron-pushing, substitution and elimination, addition reactions, and multi-step synthesis. Organic rewards understanding why a reaction proceeds — where the electrons go — rather than memorising products, and that's exactly how our organic specialists approach it.

Beyond the core sequence

Biochemistry, analytical chemistry and the chemistry components embedded in nursing and allied-health programs, matched to experts at the appropriate level. Tell us the exact course and we'll confirm the fit.

The platforms chemistry homework lives in

Online chemistry runs heavily on adaptive systems, each designed to reward genuine mastery.

Systems like ALEKS and OWLv2 are strict about significant figures and units — a numerically correct answer marked wrong for the wrong number of sig-figs is a classic chemistry frustration. We work to those conventions precisely. Deeper platform detail is on our platforms hub.

Lab reports and calculations

Online chemistry usually keeps a lab component, whether through virtual labs, provided datasets, or at-home kits. Lab reports follow a required structure — purpose, procedure, data, calculations, results and discussion — and reward correct data handling and honest error analysis over a tidy-looking conclusion. We build them to that structure, carrying units through every calculation and tying the discussion back to the actual results. Where the assignment provides data to analyse, we handle the calculations with the same dimensional-analysis discipline we apply everywhere in chemistry.

Who comes to us for chemistry

Rarely chemistry majors. Far more often it's the pre-nursing or allied-health student for whom chemistry is a required gateway to a clinical program, the biology or environmental-science student meeting a chemistry requirement, and the returning adult for whom the math-and-units combination is a genuine barrier even when the concepts make sense. In most cases chemistry is a hurdle on the way to something else — and clearing it cleanly, without it derailing an otherwise strong record, is a perfectly reasonable goal.

Chemistry is three courses in one enrolment

A chemistry course typically has three separately assessed components, and students commonly fail one while doing well in the others.

Lecture carries the concepts and most of the exam weight. Laboratory is a parallel course with its own attendance requirement, its own reports, and — importantly — its own pass condition at many institutions, meaning a failed lab fails the whole course regardless of lecture performance. Recitation or problem sessions carry the quantitative drilling and often a participation mark.

The lab is where the surprises happen. Reports are marked on structure and error analysis rather than on whether the experiment worked, and a perfectly executed experiment written up badly scores below a failed experiment analysed honestly. Percent error, sources of systematic versus random error, and significant figures propagated correctly through a calculation are where lab marks actually sit.

Online and hybrid chemistry courses handle the lab through simulations, video-based observation with provided data, or at-home kits. The write-up requirements do not soften — if anything they intensify, since the report is the only evidence of engagement.

“Pay someone to do my chemistry class” — and why the lab part changes the answer

Chemistry splits cleanly into work that can be handed over and work that cannot. Problem sets, mechanisms, stoichiometry, the written lab report built from data you collected — those are ordinary coursework. Physically running a lab, or a practical you are meant to perform, is not, and we will say so rather than quietly finding a way around it.

The topics that stop people

Equilibrium and organic mechanisms are worth singling out, for opposite reasons. Equilibrium is where general chemistry students who were coping stop coping. Organic mechanisms defeat students who were good at general chemistry precisely because the skill being tested changed without warning.

Significant figures, units and the marks they eat

More chemistry marks are lost to presentation than to chemistry. Platforms like Mastering Chemistry and ALEKS enforce significant figures strictly, and instructors marking written work usually do too.

The rules that cost the most: significant figures determined by the least precise measurement in a multiplication or division, but by decimal places in addition and subtraction; exact conversion factors not limiting precision; units carried through every line rather than appended at the end; and states of matter required in equations where the course asks for them. None of this is difficult. All of it is forgotten under time pressure.

We treat notation as part of the work rather than an afterthought, because on a platform that marks the string rather than the reasoning, it is the difference between full marks and none.

Running a chemistry course with us

The first thing we establish is the three-way split — what the lecture, lab and recitation components are each worth, and whether the lab carries an independent pass requirement. A student focused entirely on lecture material while a lab report backlog accumulates is heading for a specific and avoidable failure.

Weekly problem sets and platform homework we carry at a consistent standard with significant figures and units handled properly. Lab reports we write to the structure your course specifies, with genuine error analysis rather than a generic discussion section — and where you have collected your own data, from your data rather than from idealised values.

For preparation, chemistry rewards worked examples more than reading does. Our solutions are set out step by step with the reasoning visible, because chemistry exams reuse problem structures with different substances, and a student who has followed twenty worked stoichiometry problems is in a materially different position from one who has read the chapter twice.

Where the course has proctored exams — common in chemistry — we will say so plainly and weight the work toward preparation and toward carrying the coursework so your own time goes to the exam.

Which chemistry course are you actually in?

The word covers courses with very different demands, and the right support differs accordingly.

Introductory or preparatory chemistry is the algebra-light entry course, often required before general chemistry for students without a strong background. Volume is moderate; the obstacle is usually the quantitative reasoning rather than the chemistry.

General Chemistry I and II is the standard two-semester sequence and the source of most requests. The first semester runs from atomic structure through stoichiometry, bonding and thermochemistry; the second is dominated by kinetics, equilibrium, acids and bases, thermodynamics and electrochemistry. The second semester is substantially harder and the attrition reflects it.

Organic Chemistry I and II is the course with a reputation, and largely deserves it — though not for the reason students expect. It is not more mathematical; it is less. The difficulty is that it rewards pattern recognition and mechanistic reasoning over calculation, so the study methods that carried a student through general chemistry stop working. Students who memorise reactions fail; students who learn to push electrons pass.

Biochemistry sits between chemistry and biology, is heavily memorisation-based in its metabolic pathways, and is usually taken by students on health-professional tracks.

Analytical and physical chemistry are for chemistry majors and are respectively instrument-and-error-heavy and mathematically demanding at the level of differential equations.

For pre-medical, pre-pharmacy and pre-dental students specifically, general and organic chemistry are directly examined again on the MCAT, DAT or PCAT. That is worth weighing before deciding how much of the course to outsource — the admissions test is proctored, and it will test this material whether or not it was learned the first time.

Lab reports, and what actually earns the marks

Lab reports are the most commonly mishandled component of a chemistry course, because students write them as an account of what happened rather than as an argument about what the data show.

The structure is near-universal — purpose, procedure, data, calculations, results, discussion, conclusion — and the marks are not evenly spread across it. Procedure is usually worth little and is where students spend the most effort, rewriting the manual in past tense. Discussion is usually worth the most and is where they spend the least.

What a discussion section needs to do is specific. State the result against the accepted or expected value and quantify the discrepancy as percent error. Then identify sources of error and, crucially, distinguish systematic from random — a miscalibrated balance biases every measurement in one direction, while reading a meniscus inconsistently scatters them. Then say which direction each error would push the result. "Human error" as a catch-all earns nothing in any rubric we have seen.

Two further habits matter. Significant figures must propagate correctly through the calculations and into the stated result — a result quoted to six figures from data measured to three is wrong regardless of the arithmetic. And where the experiment did not work, the honest write-up scores better than an invented one. Instructors know what the reaction should have yielded, and data that matches the textbook too closely is more suspicious than data that does not.

Where you have run the experiment and collected your own numbers, send us those and we will write the analysis from them. Where the course supplies data or uses a simulation, we work from what it gives you. What we will not do is fabricate results for an experiment that was supposed to be performed — that is the one thing in a lab course that is genuinely indefensible, and it is also the easiest for an instructor to spot.

The situations we see most

Chemistry sits on more required-course lists than almost any science, so the students asking for help want quite different things.

Nursing and allied health students facing a one-semester chemistry requirement that is unlike the rest of their programme. Terminal, and the goal is usually to clear it without it consuming the semester their clinical courses need.

Pre-medical and pre-pharmacy students for whom general and organic chemistry are both prerequisites and admissions-test content. We are more direct with this group about the trade-off, because the MCAT and PCAT will test this material under proctoring regardless of how the course went.

Engineering students taking a required general chemistry sequence outside their main interest, usually alongside a heavy maths and physics load. The obstacle is time rather than capability.

Students repeating organic. This is a distinct and common group. Organic chemistry has a high repeat rate and the second attempt usually needs a change of method rather than more hours — moving from memorising reactions to working mechanisms, which is a different activity entirely.

If you are in that last group, the most useful thing you can tell us is what your first attempt actually looked like: whether you were keeping up with problem sets and failing exams, or falling behind on the volume. Those are different failures with different fixes, and the distinction shapes everything we would suggest.
